The M02044 is a highly integrated high-gain limiting amplifier that can be used with the same board layout and footprint as the MC2044C (refer to 02044-APP-001-A where A is the revision which will change if the application note is revised). Featuring PECL outputs, the M02044 is intended for use in applications from 100 Mbps to 622 Mbps. Full output swing is achieved even at minimum input sensitivity. The M02044 can operate with a 3.3V or 5V supply. Included in the M02044 is a programmable signal-level detector, allowing the user to set thresholds at which the logic outputs are enabled. The signal detect function has typically 2 dB (optical) of hysteresis which prevents chatter at low input levels. A squelch function, which turns off the output when no signal is present, is provided by externally connecting the LOS Status output to the JAM input. The M02044 has CMOS Status and LOS outputs.
